Storage time:
1.The operation of Temperatures and RH are : 5 ℃~35℃,RH<60%.
2.Once the package is opened, the products should be used within a week.
Otherwise, they should be kept in a damp proof box with descanting agent.
Considering the tape life, we suggest our customers to use our products within
a year(from production date).
3.If opened more than one week in an atmosphere 5 ℃ ~ 35℃,RH<60%,
they should be treated at 60 ℃± 5 ℃fo r 15hrs.
Drive Method:
LED is a current operated device, and therefore, require some kind of current limiting incorporated into
the driver circuit. This current limiting typically takes the form of a current limiting resistor placed in series
with the LED.
Consider worst case voltage variations than could occur across the current limiting resistor. The forwrd
current should not be allowed to change by more than 40 % of its desired value.

LED
(A) Recommended circuit.
(B) The difference of brightness between LED could be found due to the VF-IF characteristics of LED.
Cleaning:
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED.
ESD(Electrostatic Discharge):
Static Electricity or power surge will damage the LED. Use of a conductive wrist band or anti-electrosatic
glove is recommended when handing these LED. All devices, equipment and machinery must be properly
grounded.

Mounting:
1. If the leads are subjected to stress during soldering
a printed circuit board, illumination failure may result
immediately or later during use. For this reason,
make sure that the intervals between the installation
holes in the board are equal to the intervals between
the leads (after forming if done) so that no stress is
applied to the lead.

2. The LED lamps are designed for high-density mounting and have a structure which can alleviate mechanical stress due to clinching . Nevertheless , take care
to avoid the occurrence of residual mechanical stress
due to clinching .
